Abstract

In most of the constraint-based approaches to planning, the problem is unfolded over a given number of steps. Because this unfolded CSP encoding is very time and memory consuming, we propose on top of the CNT framework (Constraint Networks on Timelines) a more efficient slice CSP encoding which allows only a limited number of steps to be considered at each step of the search.
